Abstract

The present work aims to increase the efficiency of the medical facemask to resist covid-19 by proposing the separation of the three layers of polypropylene (PP) by fibers and beads of polymeric materials. This procedure can increase the negative electrostatic charge (ESC) generated from the triboelectrification of the PP layers of the medical facemask by the air friction when it goes through to repel the negative charged viruses such as Covid-19 out of the facemask. Besides, ESC increase can lead to the increase of the electric field in front of the facemask enhancing its function to repel the viruses. The role of separating the PP layers by polyester (PET) fibers as well as glass, polycarbonate (PC) and polystyrene (PS) beads on the magnitude of the ESC is investigated.
 
The observations of the present experiments showed that inserting fibers or beads of different materials between the PP layers increased both the air gap between them and the surface area of layers. When the air passed through the PP fibers they get negatively charged, where the magnitude of ESC increased as the triboelectried area increased. The presence of air gap increased the ability of air to be ionized and the electric field might be generated. When the magnitude of ESC increases, the electric field increases, where its ability to repel negative charged viruses increased and prevented them from going back during inhalation. As result of that, the efficiency of the PP medical facemask to resist covid-19 increased.
